IMPROVEMENT IN HINGES FOR AWNING-BLINDS.

Specification forming part of Letters Patent No. 218, 133, dated August5, 1879 application filed May 12, 1879.

To all whom it may concern.-

Be it known that I, EZEKIEL P. PIERCE, of Cambridge, in the county ofMiddlesex and State of Massachusetts, have invented certain Improvementsin Fixtures and Fastenin gs for Blind-Awnings; and I do hereby declarethat the following is a full and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon.

With reference to the drawings, Figure l is a view in perspective of ablind-awning attached to a window casing or frame, and illustrating myimprovements in fixtures and fasteniugs for the same. Fig. 2 is aninside elevation of the blind, the slats being omitted and representingthe parts in connection in elevation. Fig. 3 is an elevation of thesame, the view being taken at right angles to that of Fig. 2. Fig. 4is acorresponding elevation of the upper journal-hook, c, and the lowerhanger, 0, attached to the window frame or casing, J.

In the views like letters refer to like or corresponding parts.

a b c is a double or compound hinge, part a. being screwed to the top ofthe blind and iournal-hook 0 being fast to the window-frame or casing.The intermediate part, b, is hinged to part a and also to part c. Thehinge-connection with part c is to allow the blind to swing on avertical axis, as usual, and that with part a is to allow the blind toswing on a horizontal axis as an awning. The novel feature in thisdouble hinge is in the construction of part b with aprojecting lug, d,which, when the blind is closed or is used as an awning, comes under apart of the journahhook c, and prevents it from getting disconnected bythe lifting power of the wind or other cause; but when the blind isswung open this lug d swings therewith out from under the journal-hookc, and leaves the blind free to be lifted off in the usual manner.

The blind as an awning is held open by hooks a, hinged to the blind andhooked in an eye attached to the window casing or frame. This hook maybe of any desired length to give a suitable shape to the awning.

The lower hinge of the blind is marked f, and is provided with ajournal-pin made to slide up and down freely in it, and the lowerhanger, e, is provided with a hole or socket to receive this pin, sothat when the two are brought together and the pin dropped down theybecome a complete hinge for the lower end of the blind.

The lower hanger is constructed with a horizontal seat for hinge f, andhas also an upright concave guide for the same, so that as the two cometogether they will meet and be held in proper position to receive thesliding journal-pin g.

A bell-crank, h, arranged in connection with the hinge affords the meansby which the operator within may readily lift the pin 9 to open theawning, or drop it down to secure it in the closed position, where itmay be operated as a blind.

I claim 1. The double-jointed hinge a b c, the part 12 thereof providedwith lug d to catch under the part c and prevent lifting off,substantially as described.

2. The lower hinge, consisting of parts 6 f, constructed as described,part c having an eye with which the movable pintle engages, a horizontalseat, and an upwardly-projecting concave guide, upon which part f restswhen in engagement, substantially as set forth.

3. The combination of the journal-pin g, the bell-crank h, and thehanger e in blind-awning fixtures and fastenings, substantially asshown.
